        Features:

        • Direct 4 to 20 mA Proportional Loop Output
        • Specialized MOD:289549-17 Target Calibration
        • Built-in Safety Not OK and Signal Defeat Circuits
        The Bently Nevada 990-05-XX-01-00 MOD:289549-17 functions as a loop-powered transmitter converting probe signals into standard 4-20 mA data. This allows direct analog mapping to any standard PLC or DCS terminal block, saving massive panel space and eliminating expensive rack-monitoring architectures.

        Equipped with the specialized MOD:289549-17 factory modification, this transmitter provides calibrated electrical compensation. It actively maintains an incremental scale factor of 7.87 mV/µm (200 mV/mil) over a 1.4 mm linear range, preventing phase distortion or cross-talk across your machinery target.

        To protect against false asset trips, the Bently Nevada 990-05-XX-01-00 MOD:289549-17 integrates an automated Not OK signal defeat circuit. If a field probe fails or a coaxial cable becomes loose, the loop output drops below 3.6 mA within 100 microseconds to suppress false machinery alarms.

        The 990-05-XX-01-00 MOD:289549-17 Bently Nevada 2-Wire Vibration Transmitter may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Description
        The Bently Nevada 990-05-XX-01-00 MOD:289549-17 combines an eddy current proximity sensor and a signal conditioner into a single integrated unit, eliminating the need for an external Proximitor housing. It accepts input from a non-contacting 3300 NSv proximity probe and its matching extension cable, processing raw physical displacement into precise peak-to-peak vibration amplitude engineering units. This continuous 4 to 20 mA industry-standard current loop interfaces directly with PLCs, DCS networks, or SCADA platforms where machinery protection alarming and interlocking logic occurs.

        For maintenance engineers, the Bently Nevada 990-05-XX-01-00 MOD:289549-17 includes non-isolated PROX OUT and COM terminals alongside a premium coaxial connector. This dedicated path outputs dynamic vibration and gap voltage signals, enabling seamless machinery troubleshooting via portable, battery-powered test equipment. The custom factory modification designated by MOD:289549-17 fine-tunes internal parameters to maintain measurement stability under specialized industrial conditions, avoiding calibration drift.

        Designed with a rugged potted construction, the Bently Nevada 990-05-XX-01-00 MOD:289549-17 excels in high-humidity plant rooms and up to 100% condensing environments. External, non-interacting zero and span potentiometers are situated directly under the transmitter label to streamline loop adjustments. A dedicated test input pin allows field crews to inject signals via a function generator, achieving rapid loop output verification without pulling the machinery sensor out of service.

        Technical notes
        The Bently Nevada 990-05-XX-01-00 MOD:289549-17 requires a regulated DC power supply ranging from +12 to +35 Vdc at the terminal block to maintain loop integrity and support maximum loop resistances up to 1,000 ohms. Field calibration and diagnostic signal extraction are efficiently handled via non-interacting zero and span potentiometers alongside a dedicated non-isolated coaxial PROX OUT port.

        FAQS

        The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
        VIEW ALL FAQS
        How does the Bently Nevada 990-05-XX-01-00 MOD:289549-17 handle diagnostic signaling during a field probe failure?
        If a proximity probe fails or a cable connection loosens, the onboard Not OK/signal defeat circuit of the Bently Nevada 990-05-XX-01-00 MOD:289549-17 triggers instantly. It drives the current loop output down to less than 3.6 mA within 100 microseconds, allowing the connected PLC or DCS to identify a sensor hardware fault rather than an actual high machinery vibration event.
        Can we tap the BNC port of the Bently Nevada 990-05-XX-01-00 MOD:289549-17 without altering the 4-20 mA process variable sent to the DCS?
        The PROX OUT coaxial connector on the Bently Nevada 990-05-XX-01-00 MOD:289549-17 provides a non-isolated dynamic signal that can connect to battery-powered or isolated test gear. However, because it is not isolated from the 4-20 mA loop, Bently Nevada strongly recommends using the 122115-01 Test Adapter when connecting AC-powered oscilloscopes to prevent false loops or alarms.
        What specific physical probe configuration must be paired with the Bently Nevada 990-05-XX-01-00 MOD:289549-17?
        The Bently Nevada 990-05-XX-01-00 MOD:289549-17 is built to exclusively accept inputs from a non-contacting 3300 NSv proximity probe and its matching 5-meter or 7-meter extension cable. Attempting to attach standard 3300 XL 8mm probes will degrade electrical matching and scale factor compliance, resulting in compromised machinery protection.
        What unique field conditions does the "MOD:289549-17" suffix address on the Bently Nevada 990-05-XX-01-00 MOD:289549-17?
        The MOD:289549-17 suffix identifies a factory-validated special modification applied to the base Bently Nevada 990-05-XX-01-00 MOD:289549-17 hardware. This modification overrides default circuit values to adapt the transmitter for non-standard target metals, specialized system lengths, or custom calibration parameters required by specific high-speed compressor or machinery OEMs.
        What mounting rules must be observed to ensure the Bently Nevada 990-05-XX-01-00 MOD:289549-17 maintains compliance in high-moisture environments?
        Thanks to its potted construction, the Bently Nevada 990-05-XX-01-00 MOD:289549-17 handles up to 100% condensing humidity environments. Technicians must ensure proper physical protection of the field coaxial connectors using specialized environmental boots or seal assemblies to block moisture ingress across the high-frequency eddy-current path.
